Thank you, Marty!
It was ACROS 100 ... not the II version ... that carried an expiration date of November 2016; I rated it ASA 100, should probably have rated it ASA 80. I have five more rolls. It was processed in HC-110 diluted 1:49, 8 min @ 70°F in an Agfa Rondix tank with continuous agitation. That's pretty much my standard processing for almost all films except for the Washi rice paper film and Ferrania P30 (which I find needs lower concentration, like 1:99, and double the processing time to tame its contrast).
It is in some ways quite amazing to me how this 80 year old camera still feels remarkably modern. 🙂
